A substantial export flux of particulate organic carbon linked to sinking dead copepods during winter 2007–2008 in the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
A substantial export flux particulate organic carbon linked sinking dead copepods during 2007–2008 the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
2014/4/2
In the Arctic Ocean, vertical fluxes of particulate organic carbon (POC) remain low during the dark winter period because POC fluxes are derived from photosynthetic production. Passively sinking dead ...
The role of effective discharge in the ocean delivery of particulate organic carbon by small, mountainous river systems
The role of effective discharge in the ocean delivery particulate organic carbon by small mountainous river systems
2014/4/16
Recent research has shown that small, mountainous river systems (SMRS) account for a significant fraction of the global flux of sediment and particulate organic carbon (POC) to the ocean. The enormous...
Particulate organic carbon (POC) in relation to other pore water carbon fractions in drained and rewetted fens in Southern Germany
organic carbon pore water carbon fractions drained and rewetted fens Southern Germany
2010/1/18
Numerous studies have dealt with carbon (C) contents in Histosols, but there are no studies quantifying the relative importance of the individual C components in pore waters. For this study, measureme...
Tracing13 C-enriched dissolved and particulate organic carbon in the bacteriacontaining coral reef spongeHalisarca caerulea: Evidence for DOM feeding
Tracing13 C-enriched dissolved particulate organic carbon bacteriacontaining coral reef spongeHalisarca caerulea =DOM feeding
2014/4/18
Here we report on the trophodynamics of the bacteria-containing coral reef sponge Halisarca caerulea. The assimilation and respiration of the13 C-enriched substrates glucose, algal-derived dissolved a...
Relationships between the surface concentration of particulate organic carbon and optical properties in the eastern South Pacific and eastern Atlantic Oceans
surface concentration particulate organic carbon optical properties eastern South Pacific
2010/1/15
We have examined several approaches for estimating the surface concentration of particulate organic carbon, POC, from optical measurements of spectral remote-sensing reflectance, Rrs(λ), using field d...
Modelling carbon overconsumption and the formation of extracellular particulate organic carbon
carbon overconsumption formation extracellular particulate organic carbon
2010/1/14
During phytoplankton growth a fraction of dissolved inorganic carbon (DIC) assimilated by phytoplankton is exuded in the form of dissolved organic carbon (DOC), which can be transformed into extracell...
Differential uptake of dissolved and particulate organic carbon by the marine mussel Perna viridis
Differential uptake of dissolved particulate organic carbon marine mussel Perna viridis
2014/5/19
We used radiotracers in laboratory experiments to determine the organic carbon uptake by the marine mussel Perna viridis from different diets (phytoplankton and detritus) and from the dissolved phase ...
Bacterioplankton distribution and production in the bathypelagic ocean: Directly coupled to particulate organic carbon export?
Bacterioplankton distribution production
2014/5/20
A recently published evaluation of bacterioplankton abundance and productivity in the bathypelagic North Pacific
suggests that these properties are generally coupled with particulate organic ca...
Does 234Th/238U disequilibrium provide an accurate record of the export flux of particulate organic carbon from the upper ocean?
234Th/238U disequilibrium provide accurate record particulate organic carbon the upper ocean
2014/5/20
The magnitude of the flux of biogenic particulate organic carbon (POC) exported from the surface waters of the world ocean and remineralized at depth is critical to constraining models of the global c...
